Airborne gases get sucked into stubborn smog particles from which they cannot escape, according to findings by UC Irvine and other researchers published today in the Proceedings of the National Academy of Sciences.

A new University of Colorado Boulder-led study appears to answer contentious questions about the onset and cause of Earth's Little Ice Age, a period of cooling temperatures that began after the Middle Ages and lasted into ...

(PhysOrg.com) -- Last month it was announced that a group of researchers had come together to start a geoengineering project called Stratospheric Particle Injection for Climate Engineering (SPICE). Its aim was, and still ...

(PhysOrg.com) -- Three studies by a University of California, Davis, air-quality research group are adding to the growing body of data suggesting that very fine and ultra-fine airborne metal particles are closely linked to ...

(PhysOrg.com) -- What happens when tiny seawater particles are intentionally injected into low clouds over the ocean? To answer this question, scientists at Pacific Northwest National Laboratory and the National Oceanic and ...

Aerosol particles, including soot and sulfur dioxide from burning fossil fuels, essentially mask the effects of greenhouse gases and are at the heart of the biggest uncertainty in climate change prediction. New research from ...

Turns out, polluted air from San Francisco is not the culprit. It's a thermal trough pushing north from Arizona. In a surprise result, scientists found that this weather pattern significantly affects the chemistry of fog ...

(PhysOrg.com) -- A long, frustrating search for the source of "extra" aerosols seen in field experiments but not in models might have come to an end when scientists at Pacific Northwest National Laboratory and Imre Consulting ...

(PhysOrg.com) -- Earths climate continues to change at a rapid pace. Last week, NASA announced that 2010 was tied as the warmest year on record. Likewise, the last decade was the warmest in the 130-year global temperature ...

(PhysOrg.com) -- There's a lot more to the atmosphere than air. With every breath, we inhale a nearly invisible mish mash of tiny particles known as aerosols. From droplets of water and trace gases like sulfuric acid to specks ...
